The therapy is typically delivered in hospitals, specialized clinics, or wellness centers. It is often used in combination with other treatments, depending on a patient’s medical needs. While HBOT has been researched for decades, interest in its applications has expanded in recent years.

Importance – Why hyperbaric oxygen therapy matters today

Hyperbaric oxygen therapy is important because it addresses a wide range of health issues linked to low oxygen supply in the body. In modern healthcare, oxygen delivery to tissues is critical for healing. HBOT is particularly significant for:

• Wound care: Patients with diabetic foot ulcers or chronic wounds may benefit from enhanced oxygen supply.

• Infections: Certain bacterial infections respond better when treated with additional oxygen support.

• Neurological conditions: Researchers are studying how HBOT may influence brain injury recovery and post-stroke healing.

• Emergency medicine: HBOT remains a proven option for treating decompression sickness and carbon monoxide poisoning.

For patients and healthcare providers, the therapy represents an additional tool that can potentially improve outcomes where traditional treatments alone may not be enough.

Recent updates – Developments and trends in the past year

Over the past year, there has been growing research and public interest in HBOT. In 2024, several studies highlighted new areas where HBOT might be useful:

• Post-COVID recovery: Researchers have explored whether HBOT can help people experiencing long-term COVID-19 symptoms, especially those related to fatigue and breathing.

• Sports medicine: Elite athletes and sports organizations have shown interest in HBOT as a recovery aid, although findings remain mixed.

• Expanded clinical trials: Clinical trials in 2024 looked at HBOT for neurological conditions such as traumatic brain injury and stroke rehabilitation.

• Technology improvements: Portable hyperbaric chambers have gained popularity, offering more accessibility, though their effectiveness compared to medical-grade chambers remains under discussion.

The therapy is still considered a specialized treatment, and ongoing studies are shaping how it might be more widely applied in the future.

Laws or policies – Regulations around hyperbaric oxygen therapy

The use of hyperbaric oxygen therapy is closely regulated, as it is classified as a medical procedure. Policies vary depending on the country:

• United States: The Food and Drug Administration (FDA) approves HBOT for specific conditions such as decompression sickness, carbon monoxide poisoning, and chronic non-healing wounds. Using it outside these approved cases is considered “off-label.”

• European Union: HBOT is covered under medical device and treatment safety regulations. Coverage under public healthcare systems varies by country.

• India: HBOT is available in private hospitals and specialty centers, but its availability under public health insurance is limited.

• Insurance policies: In many countries, insurers cover HBOT only for approved medical indications, not for wellness or experimental use.

Patients are advised to seek treatment only from certified facilities that follow medical safety standards.

Tools and resources – Helpful options for patients and professionals

For those interested in learning more or accessing HBOT safely, several tools and resources are available:

• Medical directories: Hospital and clinic websites often list specialized HBOT facilities.

• Research databases: PubMed and clinicaltrials.gov provide updates on the latest HBOT studies.

• Professional associations: Organizations such as the Undersea and Hyperbaric Medical Society (UHMS) provide guidelines and educational materials.

• Informational resources:

  • World Health Organization (WHO): Reports on oxygen therapy applications.

  • FDA website: Official list of approved HBOT uses.

• Apps and tools: Some healthcare apps allow patients to track wound healing progress or log HBOT sessions.

Here’s a simplified comparison of common HBOT uses:

FAQs about hyperbaric oxygen therapy

What conditions is hyperbaric oxygen therapy officially approved for?
HBOT is approved for decompression sickness, carbon monoxide poisoning, non-healing diabetic wounds, and certain infections. Other uses are still under research.

Is hyperbaric oxygen therapy safe?
When performed in certified medical facilities under professional supervision, HBOT is considered safe. Risks can include ear pressure problems or oxygen toxicity if not properly managed.

How long does a typical HBOT session last?
A standard session usually lasts between 60 and 120 minutes. The number of sessions required depends on the condition being treated.

Does insurance cover hyperbaric oxygen therapy?
Coverage depends on the country and insurer. In most cases, only approved uses are covered, while experimental or wellness applications may not be reimbursed.

Can HBOT be done at home with portable chambers?
Portable chambers are available, but they do not reach the same pressure levels as medical-grade chambers. Their effectiveness is still being studied, and they should not replace hospital-based treatments for serious conditions.

Final thoughts

Hyperbaric oxygen therapy is a specialized medical treatment that continues to evolve in its applications. While it remains best known for treating divers and carbon monoxide poisoning, research has expanded its relevance to wound care, neurological conditions, and post-viral recovery. Regulations ensure that the therapy is applied safely, but coverage and access vary across countries.

For individuals considering HBOT, the most important step is consulting a licensed healthcare provider to determine whether it is appropriate for their condition. With ongoing research and technological development, HBOT may continue to grow as an important medical tool in the years ahead.
